TDK

TDK Corporation, commonly known as TDK, is a Japanese multinational electronics company headquartered in Tokyo. It manufactures electronic components and data-storage media, and supplies modules and sensors for a range of industries. Core product lines include passive components such as ceramic and film capacitors, inductors, and ferrite products; magnetic data storage media and read/write heads; and sensors, power modules, and other components for automotive, industrial, communications, and consumer electronics applications.

TDK was founded in 1935 as Tokyo Denki Kagaku K.K. The acronym TDK derives from that name. The company initially produced ferrite magnets for radio equipment and later expanded into broader passive components and magnetic devices. In 2009 it acquired EPCOS, a German supplier of capacitors and inductors, integrating it into its business. In 2017 TDK acquired InvenSense, a MEMS sensor specialist, to extend its sensor capabilities.

Today TDK's operations are organized into segments including Passive Components, Magnetic Recording Media, and Sensors and Power. It supplies ceramic and film capacitors, inductors, and EMI suppression components, as well as magnetic tapes, heads, and other data-storage media. Its MEMS sensors, power solutions, and automotive-grade components address markets such as consumer electronics, communications, industrial equipment, and autonomous and electrified vehicles.

TDK maintains a global manufacturing and R&D footprint across Asia, Europe, the Americas, and other regions, supporting customers worldwide. It is listed on the Tokyo Stock Exchange and is a major supplier to the electronics, automotive, and information technology sectors.
